CLEANING AND INSPECTION (Continued)
Check coolant concentration for recommended
protection level using Rotunda Battery and Antifreeze
Tester 0 1 4-R 1 060 or equivalent. If concentration is
low, partially drain the cooling system and add 1 00
percent antifreeze solution such as Premium Cooling
System Fluid E2FZ - 1 9549-AA or -8 (in Oregon,
F5FZ- 1 9549-CC; in Canada, CXC-8-8), recycled
coolant or equivalent meeting Ford specification
ESE-M97B44-A, to obtain the recommended
protection level.
Cooling System Hoses and Clamps
1 . Inspect cooling system hoses and clamped hose
connections for leaks or excessive deterioration.
Service or replace as required.
2. lnspeet radiator core and tanks for leaks. Service
or replace as required.
3. Inspect cooling system hose routing to ensure
sufficient clearance to engine compartment
components. Reposition hoses if required.
4.
Check radiator supports ( 1 6 1 38) and brackets
for firm radiator retention. Correct as required.
The radiator (8005) is installed with rubber
isolation mounts.

Cooling System Draining, Filling and

Bleeding
1 . WARNING: NEVER REMOVE RADIATOR OR
COOLING SYSTEM CAP UNDER ANY
CONDITIONS WHILE ENGINE IS OPERATING.
FAILURE TO FOLLOW THESE INSTRUCTIONS
COULD RESULT IN PERSONAL INJURY
AND/OR DAMAGE TO THE COOLING
SYSTEM OR ENGINE.
WARNING: TO AVOID BURNS FROM
SCALDING COOLANT OR STEAM, USE
EXTREME CARE WHEN REMOVING THE
RADIATOR PRESSURE CAP.
With the engine off and sufficiently cool, remove
pressure relief cap or radiator cap (8 1 00), open
radiator draincock (8 1 1 5) and remove the
cylinder block drain plugs (if equipped). Allow
coolant to drain.
2. Close radiator draincock. Hand-tighten.
3. Check all hose clamps for proper tightness and
location. Make sure radiator draincock is closed
and cylinder block drain plugs are installed (if
equipped).
Engine Cooling
4.
Place heater temperature selector in maximum
heat position.
5. CAUTION: The vent plug must be removed
before radiator fill or the engine
completely. Do not turn plastic cap under
vent plug or the gasket may be damaged. Do
not try to add coolant through vent plug hole.
Install vent plug after filling radiator
and before starting engine.
Remove vent plug on water bypass elbow
(located on intake manifold (9424) behind water
hose connection (8592)) on 3.8L engines.
6. NOTE: It important to maintain engine coolant
concentrate between 40 percent, -24° C (-1 1 ° F)
and 60 percent -52 °C (-62 ° F), depending on
climate conditions. Below 40 percent, there is a
los � of freeze protection. Above 60 percent, the
engme may overheat on a warm day. Outside this
range, protection against rust and corrosion may
be greatly reduced. Refer to Specifications for
specified coolant.
Fill engine cooling system with 50 / 50 mixture of
water and Premium Cooling System Fluid
E2FZ- 1 9549-AA or -8 (in Oregon,
F5FZ- 1 9549-

PERSONAL INJURY OR DAMAGE TO THE
VEHICLE, DO NOT OPERATE ENGINE WITH
VEHICLE HOOD
BLADE (8600)
FOR POSSIBLE CRACKS AND SEPARATION.
Leave pressure relief cap or radiator cap off and
run engine until water thermostat (8575) opens
(coolant flowing through upper radiator hose
(8260) becomes hot).
8. Stop engine and add a 50 / 50 mixture of Premium
Cooling System Fluid E2FZ - 1 9549-AA or
Oregon, F5FZ- 1 9549-CC; in Canada, CXG-8-B),
recycled coolant or equivalent meeting Ford
specification ESE-M97844-A and water to the
FULL HOT mark on the radiator coolant recovery
reservoir (8A080) on 3.8L engines or degas
bottle on 4.6L (2V) engines.
9. Install pressure relief cap or radiator cap.
